The CPU_FAN connector supports the CPU fan of maximum 1A (12 W) fan power.
The CPU_FAN connector and CHA_FAN 1-3 connectors support the ASUS FAN Xpert
2 feature.
If you install two VGA cards, we recommend that you plug the rear chassis fan cable
to the motherboard connector labeled CHA_FAN1-3 for better thermal environment.
Do not forget to connect the fan cables to the fan connectors. Insufcient air ow inside the
system may damage the motherboard components. These are not jumpers! Do not place
jumper caps on the fan connectors!

Connect the fan cables to the fan connectors on the motherboard, ensuring that the
black wire of each cable matches the ground pin of the connector.
